Abstract

Disclosed is a system for monitoring chemical reactions, especially for detecting exothermic chemical reactions, comprising a reaction device consisting of a plurality of spatially separated reaction chambers for receiving reaction mixtures, and a dosing device for feeding reaction components of the reaction mixtures into the reaction chambers. The inventive system also comprises at least one sensor device which is sensitive to thermal radiation in order to detect the thermal radiation emitted by the reaction mixtures in the reaction chambers.
